【発明の属する技術分野】
本発明は、表皮材のトリミング方法及びその装置に関する。
【０００２】
【従来の技術】
従来、所定の形状に成形された基材の表面に表皮材を貼着して真空成形し、表皮材の余剰部分をトリミングするものは公知である。（例えば、特許文献１参照。）。
【０００３】
【特許文献１】
実開平６−４９０２１号公報（第１頁、第１図）
【０００４】
【発明が解決しようとする課題】
しかし、前記公報のものは、基材受け型部を樹脂製型にすると共にトリミング用の溝型部を金属製型にする必要があるため、型製作が煩雑になるという問題がある。またトリミング形状を変更する場合、前記基材受け型部及び溝型部に対向する上型（図示されない）の改造に手間がかかるという問題がある。
本発明は上記の問題に鑑みて成されたもので、型製作を簡略化することができると共にトリミング形状を変更する場合の型改造を少なくすることができる表皮材のトリミング方法及びその装置を提供することを目的とする。
【０００５】
【課題を解決するための手段】
上記の目的を達成するために本発明における表皮材のトリミング方法は、所定の形状に予め成形された基材の表面に表皮材の裏面を貼着すると共に該表皮材の表面を真空成形した後、該表皮材の余剰部分をトリミングする方法であって、前記基材を下型の基材受け部に載置して保持させる工程と、通気性のある材料で製作されると共に表皮材真空吸引機構に連通された上型と前記下型の間位置に前記表皮材を搬入する工程と、前記表皮材真空吸引 機構を作動させながら前記上型と下型を型閉じすることにより、前記基材の表面に前記表皮材の裏面を貼着すると共に該表皮材の表面を真空成形する工程と、前記上型と下型を型開きした後、下端部にトリミング用溝部が形成された中間定盤を該上型と下型の間位置に搬入する工程と、前記中間定盤と下型で前記表皮材を挟持した状態で該表皮材の余剰部分をトリミングする工程と、を有することを特徴とする。
【０００６】
また上記の目的を達成するために本発明における表皮材のトリミング装置は、所定の形状に予め成形された基材の表面に表皮材の裏面を貼着すると共に該表皮材の表面を真空成形した後、該表皮材の余剰部分をトリミングする装置であって、前記基材を受ける基材受け部を有する下型と、通気性のある材料で製作されると共に表皮材真空吸引機構に連通され、且つ、前記表皮材の意匠面形状部を有すると共に前記下型に対向する位置に配設された上型と、下端部にトリミング用溝部が形成されると共に前記上型と下型の間位置に搬入出可能に配置された中間定盤と、該中間定盤が前記上型と下型の間位置に搬入された位置における前記トリミング用溝部の下方に配設されて、前記表皮材の余剰部分をトリミングするトリミング機構と、を具備することを特徴とする。
【０００７】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて詳しく説明する。図１において、図示されない下型昇降手段に連結された下型定盤１の上部には、所定の形状に予め成形された基材Ｗ（図２参照）を受ける基材受け部３を有する下型２が取り付けられており、前記基材受け部３は基材Ｗ裏面形状と同様の形状にされている。なお該基材受け部３には図示されない吸引孔が穿設されており、該吸引孔は図示されない基材真空吸引機構に連通されている。そして、前記下型２に対向する位置には表皮材Ｒの意匠面形状部７を有する上型８が配設されており、該上型８の上部には上型定盤９が取り付けられている。なお該上型定盤９は図示されない上型昇降手段に連結されている。また前記上型８は通気性のある材料で製作されていると共に図示されない表皮材真空吸引機構に連通されている。
【０００８】
また前記上型８と下型２の間位置には搬入出可能にされた枠状の中間定盤１１が配置されており、該中間定盤１１下端部には全周に亘ってトリミング用溝部１０、１０が形成されている。なお該中間定盤１１は図示されない中間定盤搬送手段に連結されている。そして、該中間定盤１１が前記上型８と下型２の間位置に搬入された位置における前記トリミング用溝部１０、１０の下方には、表皮材Ｒ（図２参照）の余剰部分をトリミングするトリミング機構１２、１２が配設されており、該トリミング機構１２、１２は前記下型２の中空部２ａ、２ａ内に設置されている。
【０００９】
また該トリミング機構１２、１２は、トリミング刃昇降手段としてのシリンダ５、５と、該シリンダ５、５の先端に連結された刃受け台６、６と、該刃受け台６、６に取り付けられたトリミング刃４、４と、によって構成されており、該トリミング刃４、４は前記トリミング用溝部１０、１０に対応する位置に全周に亘って設置されている。
【００１０】
このように構成されたものの作動について説明する。まず、上型８と下型２が型開き状態（図１の状態）、且つ、中間定盤１１が上型８と下型２の間位置から搬出された状態で、所定の形状に予め成形された基材Ｗを基材受け部３に載置し、前記基材真空吸引機構を作動させて真空吸引により保持させる。次に図示されない表皮材搬送手段で表皮材Ｒを上型８と下型２の間位置に搬入する。そして、前記表皮材真空吸引機構を作動させながら前記下型昇降手段及び上型昇降手段を作動させて型閉じをする（図２参照）。これにより、基材Ｗの表面に表皮材Ｒの裏面が貼着されると共に表皮材Ｒ表面の真空成形が成される。
【００１１】
次に前記表皮材真空吸引機構の作動を解除し、前記下型昇降手段及び上型昇降手段を逆作動させて型開きをする（図３参照）。そして、前記中間定盤搬送手段を作動させて中間定盤１１を上型８と下型２の間位置に搬入する（図４参照）。次に前記下型昇降手段及び上型昇降手段を作動させて、上型８と下型２で中間定盤１１を挟持すると共に中間定盤１１と下型２で表皮材Ｒを挟持する。そして、シリンダ５、５を伸長作動させてトリミング刃４、４により表皮材Ｒの余剰部分（本実施形態では外周部分）をトリミングする（図５参照）。その後、シリンダ５、５を縮引作動させる。
【００１２】
次に前記下型昇降手段及び上型昇降手段を逆作動させて型開きした後、前記中間定盤搬送手段を逆作動させて中間定盤１１を上型８と下型２の間位置から搬出する。そして、前記基材真空吸引機構の作動を解除し、下型２に載置された完成製品を取り出す。
【００１３】
なお本発明ではトリミング形状を変更する場合、トリミング刃４、４及び、中間定盤１１のトリミング用溝部１０、１０の改造又は変更で対応できる。このため、上型８と下型２の型改造を大幅に少なくすることができる。特に、表皮材Ｒの意匠面形状部７を有する上型８は通気性のある材料で製作されているため、一般的に改造が困難であり、この上型８の改造が一切必要ない点は本発明の大きな利点といえる。
【００１４】
なお本発明の実施形態では、真空吸引によって基材Ｗを基材受け部３に保持させるようにしたが、これに限定されるものではなく、機械的なクランプ機構等によって保持させるようにしてもよい。
【００１５】
【発明の効果】
上記の説明から明らかなように本発明は、所定の形状に予め成形された基材の表面に表皮材の裏面を貼着すると共に該表皮材の表面を真空成形した後、該表皮材の余剰部分をトリミングする方法であって、前記基材を下型の基材受け部に載置して保持させる工程と、通気性のある材料で製作されると共に表皮材真空吸引機構に連通された上型と前記下型の間位置に前記表皮材を搬入する工程と、前記表皮材真空吸引機構を作動させながら前記上型と下型を型閉じすることにより、前記基材の表面に前記表皮材の裏面を貼着すると共に該表皮材の表面を真空成形する工程と、前記上型と下型を型開きした後、下端部にトリミング用溝部が形成された中間定盤を該上型と下型の間位置に搬入する工程と、前記中間定盤と下型で前記表皮材を挟持した状態で該表皮材の余剰部分をトリミングする工程と、を有するから、型製作を簡略化することができると共にトリミング形状を変更する場合の型改造を少なくすることができる等種々の効果がある。
